# Best Svelte File Upload Libraries Compared

**The short answer:** for a Svelte 5 uploader that sends files straight to your
own S3-compatible bucket, with cloud drives and resumable uploads, use upup or
Uppy. If you only need the drop zone, svelte-file-dropzone or the one in your UI
kit (Skeleton, Flowbite Svelte, shadcn-svelte) is the lightest start, and
FilePond gives you one polished component that posts to your server.

**Try it first:** the [live Svelte demo](/svelte/#demo) uploads a real
file from your browser, and the
[Svelte quickstart](/docs/quickstarts/svelte/) gets it running in your app.

This roundup compares the Svelte file upload libraries and drop zones that
usually come up, on the features that decide the choice, then explains how to
pick.

## The libraries

### upup

upup's `@useupup/svelte` is a native Svelte 5 port of its uploader, not a
wrapper around another framework, built on the same headless core as every
other upup package. It uploads directly to S3-compatible storage with
presigned URLs, either from your own signing endpoint or through
`@useupup/server`, and lets users pick files from the device, Google Drive,
OneDrive, Dropbox, Box, a camera, a screen capture or a link. It requires
Svelte 5. The built-in image editor is available in the React and Preact
packages only; in Svelte the editor is stubbed. See the
[Svelte file uploader](/svelte/) page for a three-step setup.

### Uppy

Uppy is a modular uploader. `@uppy/svelte` provides Svelte components for its UI
plugins: the pre-composed `<Dashboard />`, `<DashboardModal />` and
`<StatusBar />`, plus headless components and hooks for building your own UI on
Svelte 5. You install `@uppy/core` and each plugin you use. Plugins cover sources
(webcam, screen capture, remote drives through Companion, a server you host) and
destinations such as tus and S3. See [upup vs Uppy](/docs/comparisons/upup-vs-uppy/).

### FilePond

FilePond is a single animated upload component, and `svelte-filepond` is its
Svelte adapter. It posts files to your own server endpoint, supports chunked
uploads, and extends through plugins for previews, validation and image
transforms. FilePond itself is still released regularly, but the adapter's last
release, 0.2.2, was in December 2023. It was developed against Svelte 3 and
declares no Svelte version range, so test it on Svelte 5 before you commit. See
[upup vs FilePond](/docs/comparisons/upup-vs-filepond/).

### svelte-file-dropzone

svelte-file-dropzone describes itself as a Svelte implementation of
react-dropzone. It turns an area into a drop target, filters files by `accept`,
`maxSize` and `minSize`, and hands the accepted and rejected files to your
`drop` handler. It does not upload anything, so progress, retries and storage
are yours to write. It is MIT-licensed, its peer range covers Svelte 3.54, 4 and
5, and its last release, 2.0.9, was in October 2024. For the same idea in React,
see [upup vs react-dropzone](/docs/comparisons/upup-vs-react-dropzone/).

### Drop zones in UI kits

Three Svelte UI toolkits ship a drop zone you can start from. Skeleton's
`FileUpload` (in `@skeletonlabs/skeleton-svelte`) provides a dropzone, a trigger
button and a file list. Flowbite Svelte has `Dropzone` and `Fileupload`
components. shadcn-svelte extras, a community set of shadcn-svelte components,
has a `File Drop Zone` that calls your `onUpload` function with the files and
checks `maxFiles`, `maxFileSize` and `accept`. All of them select
files and stop there: the upload request, progress and storage are your code.
Skeleton and Flowbite Svelte need Svelte 5.40 or later.

### Older packages with similar names

`svelte-dropzone` has had no release since December 2019, and its GitHub
repository is archived. It is not compared above.

### A note on "Svelte file manager"

A file manager browses, renames, moves and deletes files that are already in
storage. None of the libraries above is one. upup's cloud-drive sources let a
user browse their own Google Drive, OneDrive, Dropbox or Box inside the
uploader to pick files, but they do not manage the contents of your bucket.

## How to choose

- **You want a finished uploader on your own bucket:** upup or Uppy.
- **Your users pick files from Google Drive, OneDrive, Dropbox or Box:** upup
  or Uppy. Uppy routes remote files through Companion; upup does it in the
  browser (client mode) or in `@useupup/server` (server mode).
- **You are on Svelte 4:** upup needs Svelte 5. `@uppy/svelte` and
  svelte-file-dropzone accept Svelte 4.
- **You only need a drop target:** svelte-file-dropzone, or the drop zone from
  Skeleton, Flowbite Svelte or shadcn-svelte, then write the upload code.
- **You already use FilePond elsewhere:** `svelte-filepond`, after checking it on
  your Svelte version.
- **You need image editing in Svelte:** Uppy's Image Editor plugin, or
  FilePond's plugins. upup's editor is not available in Svelte.
- **You upload very large files:** use resumable uploads, with upup or Uppy.

## Minimal upup example

Install the package:

```sh
npm i @useupup/svelte
```

Render the uploader and point it at an endpoint that returns a presigned URL:

```svelte
<script lang="ts">
    import { UpupUploader } from '@useupup/svelte'
    import '@useupup/svelte/styles'
</script>

<UpupUploader provider="aws" uploadEndpoint="/api/upload-token" />
```

upup requires Svelte 5. The [Svelte quickstart](/docs/quickstarts/svelte/)
covers the endpoint, and [Code Examples](/docs/code-examples/) has a
ready-to-copy presign handler.

## FAQ

### What is the best file upload library for Svelte?

For a complete uploader against your own storage, upup or Uppy. For only a drop
zone, svelte-file-dropzone or the one in your UI kit. For one polished component
that posts to your server, FilePond through `svelte-filepond`.

### Which Svelte upload libraries upload directly to S3?

upup, with presigned URLs from your endpoint or `@useupup/server`, and Uppy,
with its AWS S3 plugin. With the others you write the S3 signing and upload
code yourself.

### Does upup's Svelte package include the image editor?

No. The image editor ships in `@useupup/react` and `@useupup/preact` only.
Everything else, including cloud drives, camera, screen capture and resumable
uploads, works the same in Svelte.

### Do these libraries work with Svelte 5?

upup requires Svelte 5. `@uppy/svelte` accepts Svelte 4 or 5, and its headless
components and hooks are Svelte 5 only. svelte-file-dropzone accepts Svelte
3.54, 4 or 5. Skeleton and Flowbite Svelte need Svelte 5.40 or later.
`svelte-filepond` declares no Svelte range and was last released in December
2023, so test it on Svelte 5 first.

### Is there a Svelte file manager component?

None of these is a file manager. They select and upload files, and do not
browse, rename or delete files already in storage. upup can browse a user's
Google Drive, OneDrive, Dropbox or Box to pick files for upload.

### Are these libraries free?

Yes. upup, Uppy, FilePond, svelte-file-dropzone, Skeleton, Flowbite Svelte and
shadcn-svelte extras are MIT-licensed. FilePond's full image editor, Pintura, is
a separate commercial product.
